AUTOMATIC REACTOR TRIP DUE TO FEEDWATER REGULATING VALVE FAILING CLOSED
"On February 26, 2015, at 1511 EST, with Unit 1 operating at 95% power in an end of cycle coastdown, the 'B' Main Feedwater Reg Valve failed closed which resulted in a Unit 1 automatic reactor trip due to 'B' Steam Generator low/low level. The operations crew entered the reactor trip procedure and stabilized Unit 1 in Mode 3 at normal operating pressure and temperature. All control rods fully inserted into the core following the reactor trip. This reactor protection system actuation is reportable per 10CFR50.72(b)(2)(iv)(B). The Auxiliary Feedwater pumps actuated as designed as a result of the reactor trip and provided makeup flow to the steam generators. The automatic start of the Auxiliary Feedwater system is reportable per 10CFR50.72(b)(3)(iv)(A) for the valid actuation of an ESF system. The Auxiliary Feedwater pumps were subsequently secured and returned to automatic. Decay heat is being removed by the condenser steam dump system. Unit 1 is in a normal shutdown electrical lineup.
"The NRC Resident Inspectors have been notified and are in the Control Room. The Louisa County Administrator will be notified."

AGREEMENT STATE REPORT - MISSING FIXED GAUGE SHUTTER
The following report was received via e-mail:
"On 02/26/2015, the RSO for Boise Cascade called in a preliminary report [to the Louisiana Department of Environmental Quality] about a shutter missing on a gauge to be 'locked out' during a 24 hour turn-a-round. The shutter is a manual sliding port cover that has to be removed when the gauge is used on the process. The removed shutter is stored by placing it on an adjacent surface until needed. Vibrations on the process had caused the port cover to fall approximately 50 ft. below the storage locations. However, this time the cover could not be located and the gauge could not be locked out. The gauge remained on the process until it could be repaired.
"On 02/26/2015, a replacement shutter/port cover was ordered from Thermo Measuretech. The shutter was delivered on 02/27/2015 and installed the same day. There was no radiation exposure risk to the public or workers. The gauge is installed on a 50 ft. elevation and the unshielded radiation field is approximately 0.3 mR/hr at 1 ft. from the surface of the device.
"The gauge was a Texas Nuclear Device, TN 5192, s/n B3421 containing approximately 100 mCi of Cs-137 when installed during the mid-1980s.
"The Department [Louisiana Department of Environmental Quality] considers this item closed and the records will be reviewed during the next inspection."

MOLYBDENUM-TECHNETIUM GENERATOR LOST DURING SHIPMENT
A Mo-Tc Generator was sent to Baptist Hospital in Miami, Florida. The generator was used for approximately 2 weeks before being shipped back on 1/18/14. It was picked up by the common carrier on 1/19/14. The Mo-Tc generator did not make it back to the Mallinckrodt facility.
A search was initiated at the Mallinckrodt facility and Baptist Hospital. When the Mo-Tc generator could not be located, it was declared missing on 2/26/15.
The generator is approximately 65 lbs. total and contains 8.1 mCi of depleted uranium-238. The shield was stamped with the number 2116.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
